Homework Help: Damping constant

  1. May 1, 2006 #1
    The suspension system of a 1700 kg automobile "sags" 13 cm when the chassis is placed on it. Also, the oscillation amplitude decreases by 62% each cycle. Estimate the values of (a) the spring constant k and (b) the damping constant b for the spring and shock absorber system of one wheel, assuming each wheel supports 425 kg.

    Kx = mg
    K = 1281.5 N/m

    But the damping constant i am having trouble with.
    W' = Square root (K/m - b^2/4m^2) is the formula i think i use?
    = kg/s

    but both answers are wrong

    Perhaps if you showed your calculations we could help.
